CGR (and others) Robart Hinge Points are great. If I'm not using CA hinges, I use Robarts.

I too was leary of them before I tried them, but Robart makes an alignment jig for drilling the holes that takes any fear out of it.

You just hold the elevator (Or whatever) in place and draw a line across the hinge line for each hinge, then put the jig in place and drill the holes (You need to enlarge the opening of each hole slighty after drilling as the center of the hinge is slightly larger)

Now you install all of the hinges with a slow-setting glue like epoxy or gorilla glue and flex the elevator a few times to correct any misalignment of the hinge pins.

That's it!

Try it, you'll like it

As for the original question, you can repair the broken hinge without much trouble by adding a hinge made of MonoKote or Ultracote as shown below
